THE ULTIMATE MEASUREMENT TOOL FOR ULTRAFAST LASER SYSTEMS
AND HOLLOW-FIBER COMPRESSORS

The d-cycle is the system of choice for fast and accurate measurement of even the most demanding ultrafast pulses, down to ultra-broadband spectra and single-cycle durations – the shortest for any commercially available device. Its versatile and standalone architecture handles a variety of state-of-the-art ultrashort pulse sources, from broadband laser oscillators, amplifiers and OPAs to hollow-core fiber compressors. The d-cycle’s compact footprint packs a dispersion-calibrated system that measures your pulses exactly as they are, without any ambiguities. Coupling your beam into the d-cycle is easily achieved in less than one minute and a full measurement takes less than 10 seconds. The intuitiveness of the d-cycle trace provides instant visual feedback for optimisation and control of your source via d-cycle’s unique graphical user interface – the Virtual LogbookTM – and the proprietary d-scan retrieval algorithm provides fast and accurate retrieval of the complete temporal profile of the pulses.
